My DD1 is 3.2 and since the birth of DD2 (5 weeks ago) we're having major problems with her. She's cottoned on to the fact that if she's naughty, she gets attention, and consequently both me and DH are at the end of our tethers. She's chucking books off shelves, having major tantrums in public places - but also things like telling me she needs a wee, about 4 mins after I've started feeding DD2. So I stop feeding DD2, take DD1 to the toilet and she has about a teaspoon of wee.
Do we just ride this out, and put it down to the upset of DD2's arrival, or do we stop the things she likes (books at bedtime etc etc) until she gets the message?
